In may case with the Samyang, the aperture would be missing as
well. Shutter speed is there, since it's done by the body - as is
the ISO. But since the body doesn't know the aperture, as it's in
the lens, it can't calculate the EV. Would this be a consistent
constellation for manual lenses, then - EV 0 and no aperture? Then
if they occur together, maybe one could safely assume a manual
lens.
The EV isn't in the EXIF, Hugin calculates it from Shutter speed,
Aperture and ISO, and it can legitimately be zero.
Thomas just committed a fix for this, if Aperture is missing then
Hugin now assumes f/3.5. This should deal reasonably with manual
lenses, since the only credible partial-EXIF situation is where only
Aperture is missing.
